HETDEX [OII] galaxies at : Volume-limited samples and their power spectra
Jeongin Moon, Eiichiro Komatsu, Robin Ciardullo +15
The catalog from the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) Public Data Release 1 (PDR1) contains half a million emission-line-selected [OII] galaxies spread across…
Nearly Full-Sky Low-Multipole Cosmic Microwave Temperature Anisotropy: I. Foreground Cleaned Maps
Hayley C. Nofi, Graeme E. Addison, Charles L. Bennett +2
Studies of cosmic microwave background (CMB) are often limited by foreground contamination. Foreground cleaning is performed either in harmonic or pixel space after data cuts have…
Bayesian and frequentist perspectives agree on dynamical dark energy
Laura Herold, Tanvi Karwal
Baryon acoustic oscillation data from the Dark Energy Spectroscopic Instrument (DESI) show evidence of a deviation from a cosmological constant within a Bayesian analysis. In t…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Revisiting the impact of neutrino mass hierarchies on neutrino mass constraints in light of recent DESI data
Laura Herold, Marc Kamionkowski
Recent results from DESI combined with cosmic microwave background data give the tightest constraints on the sum of neutrino masses to date. However, these analyses approximate the…
Profile Likelihoods in Cosmology: When, Why and How illustrated with CDM, Massive Neutrinos and Dark Energy
Laura Herold, Elisa G. M. Ferreira, Lukas Heinrich
Frequentist parameter inference using profile likelihoods has received increased attention in the cosmology literature recently since it can give important complementary informatio…
A visual tool for assessing tension-resolving models in the - plane
Igor de O. C. Pedreira, Micol Benetti, Elisa G. M. Ferreira +2
Beyond-CDM models have been proposed to address various shortcomings of the standard cosmological model, such as the ``Hubble tension.'' These models often have an impact on the…
Bayesian and frequentist investigation of prior effects in EFTofLSS analyses of full-shape BOSS and eBOSS data
Emil Brinch Holm, Laura Herold, Théo Simon +4
Previous studies based on Bayesian methods have shown that the constraints on cosmological parameters from the Baryonic Oscillation Spectroscopic Survey (BOSS) full-shape data usin…
Constraint on Early Dark Energy from Isotropic Cosmic Birefringence
Johannes R. Eskilt, Laura Herold, Eiichiro Komatsu +3
Polarization of the cosmic microwave background (CMB) is sensitive to new physics violating parity symmetry, such as the presence of a pseudoscalar "axionlike" field. Such a field…
Discovering a new well: Decaying dark matter with profile likelihoods
Emil Brinch Holm, Laura Herold, Steen Hannestad +2
A large number of studies, all using Bayesian parameter inference from Markov Chain Monte Carlo methods, have constrained the presence of a decaying dark matter component. All such…
Resolving the Hubble tension with Early Dark Energy
Laura Herold, Elisa G. M. Ferreira
Early dark energy (EDE) offers a solution to the so-called Hubble tension. Recently, it was shown that the constraints on EDE using Markov Chain Monte Carlo are affected by prior v…
Restoring cosmological concordance with early dark energy and massive neutrinos?
Alexander Reeves, Laura Herold, Sunny Vagnozzi +2
The early dark energy (EDE) solution to the Hubble tension comes at the cost of an increased clustering amplitude that has been argued to worsen the fit to galaxy clustering data.…
New constraint on Early Dark Energy from Planck and BOSS data using the profile likelihood
Laura Herold, Elisa G. M. Ferreira, Eiichiro Komatsu
A dark energy-like component in the early universe, known as early dark energy (EDE), is a proposed solution to the Hubble tension. Currently, there is no consensus in the literatu…
The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) Survey Design, Reductions, and Detections
Karl Gebhardt, Erin Mentuch Cooper, Robin Ciardullo +60
We describe the survey design, calibration, commissioning, and emission-line detection algorithms for the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX). The goal of HETDEX…
Mukhanov-Sasaki equation in manifestly gauge-invariant linearized cosmological perturbation theory with dust reference fields
Kristina Giesel, Laura Herold, Bao-Fei Li +1
The aim of this article is to understand the role of dust reference fields, often also called clocks, on cosmological perturbations around a flat FLRW universe. We derive the Mukha…
Hard and bright gamma-ray emission at the base of the Fermi bubbles
Laura Herold, Dmitry Malyshev
The Fermi bubbles (FBs) are large gamma-ray emitting lobes extending up to in latitude above and below the Galactic center (GC). Although the FBs were discovered 8 years ago,…
